Refresh Bsp

Hi to all,

I have a bsp with a start page Indexh.htm

In this page I have a dynamic table (built with an internal table) in which users entering data and I produce a file in this way:

CALL METHOD cl_bsp_utility=>download

             EXPORTING

               object_s                                 = l_xstring

               content_type                             = app_type

               content_disposition  ='attachment;filename=file.txt''

               response                                 = _m_response

               navigation                               = navigation.

After the download I need to clear all areas of my table;

i tried with refresh my table but not work....how to clear my table after download file?...i have no idea

Thanks in advance
